The modern fire extinguisher developed by British Captain George William Manby in 1818 was composed of 3 gallons of pearl ash solution contained in a copper vessel with compressed air. Continuous development of the fire extinguisher saw it move from a simple one and into drypowder fire extinguishers. Dry powder fire extinguishers make use of powder chemicals that get sprayed at high velocities via air pressure. This type of fire extinguisher is suitable for various situations since it blankets the fire, immediately cutting off oxygen supply. This can also be used when dealing with fires caused by flammable liquids such as gasoline and oil. One major setback on this type of fire extinguisher is that it leaves a lot of residue. Well, it is better to clean up residue from a dry powder fire extinguisher than sweep the ashes from a burned house. To those who would want fewer residues, they can always opt for water fire extinguishers or CO2.
